Overview
The Electrocube RG1781-3 is a single-phase RC network designed for PC mount applications. It features a capacitance of 1 µF with a tolerance of ±10% and a resistance of 47 ohms. The component is rated for 125 VAC or 200 VDC, with a power dissipation capacity of 0.5 W. It utilizes solid wire leads of minimum #20 AWG gauge. The operating temperature range spans from -40°C to 80°C. This compact unit is suitable for general-purpose EMI/RFI filtering tasks.
Feature Summary
- Single-phase RC network configuration for circuit protection
- Compact radial package enabling side-by-side mounting
- Solid wire leads for through-hole PCB integration
Applications
- General purpose EMI/RFI suppression
- Power supply input filtering
- Motor drive noise reduction
Procurement Notes
Verify the specific voltage rating (125VAC vs 200VDC) required for your application against the datasheet specifications. Confirm lead length requirements as the specification notes a minimum length. Ensure the operating environment stays within the -40°C to 80°C thermal limits. Check for any RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a single-phase RC snubber or filter is needed for low-power AC or DC circuits. The 1 µF capacitance and 47 ohm resistance provide a specific time constant suitable for general noise attenuation. Consider the physical dimensions and lead type for PCB layout constraints. Ensure the voltage rating exceeds the peak circuit voltage.
Part Context
This part belongs to the Electrocube RG1781 series of single-phase RC networks. These components are typically used in conjunction with other Electrocube filters like the RG2030 series. The series offers various capacitance and resistance values tailored for different phase and voltage requirements in industrial electronics.
Replacement Considerations
Cross-reference with similar single-phase RC networks from other manufacturers. Verify that substitute parts match the 1 µF capacitance, 47 ohm resistance, and 200 VDC rating. Ensure the replacement supports through-hole mounting with comparable lead specifications.
